LSU announced that Mike VI, the school's live Tiger mascot, was humanely euthanized Tuesday at the age of 11 following his four-month battle with cancer.
Mike VI was diagnosed in late May 2016 with a spindle cell sarcoma, a type of cancer.
On Oct. 3, Mike was taken to the Vet School for further observation and two days later it was announced that the cancer had returned and spread. The Tiger was returned to his habitat and spent much of his last week outside.
In June, he received a precise, concentrated dose of radiation to attack the cancer. The radiation dose was delivered in a single treatment and optimized to avoid normal tissues surrounding Mike's cancer in order to reduce the risk complications. The radiation left a scar near Mike VI's right eye.
Mike VI, one of only two live tiger college mascots in the United States, was born on July 23, 2005, and came to LSU as a 2-year-old. At the time of his arrival, he weighed about 320 pounds and put on some 100 pounds during his years in the habitat.
He debuted in Tiger Stadium on the evening of the LSU-Florida game on Saturday, Oct. 6, 2007, a 28-24 LSU win en route to the 2007 National Championship.
Dr. David Baker, in charge of Mike VI's overall healthcare, has already begun a search for a young Tiger cub that can be brought to LSU to become Mike VII.
According to the University announcement, there will not be a formal memorial service for Mike VI, but fans are encouraged to share their memories, stories and photos on social media using #MikeVI.
Mike VI received well wishes from fans and fellow mascots since being diagnosed, the most recent being from Texas mascot Bevo on Friday.
